Tbh I read the research article and it's not rocket science that they were doing. Any 2nd rate FBI analyst would have come up with these ideas sooner or later to try and match anonymous profiles with veryfied ones using LLMs.

The results, especially the high numbers stated in the news article (68% recall, 90% accuracy) are overestimated as their verification method (i.e., whether the LLM detected really the right account) come from matching veryfied accounts with a test set of anonymous accounts of which they knew the real name. They knew the real name bcs the persons had a public link to their LinkedIn in their "anonymous" profile (which was removed for the sake of testing wheter the LLm can match the two acfounts. That being said: a user who uses a pseudonym but links his/her account publically to a, say, LinkedIn account doesn't really care about anonymity and might hand out many more 'breadcrumbs' to follow than a truly anonymous account.
But I still think that also in the case of a fully anonymous account, people can be fingerprinted and matched with non-anonymous identities due to language, style etc. by a LLM.
